Although the cheetah routinely lives for >12 yr in ex situ collections, females > 8 yr of age reproduce infrequently. We tested the hypothesis that reproduction is compromised in older cheetah females due to a combination of a disrupted gonadal, oocyte and uterine function/integrity. We assessed (1) ovarian response to ...

The use of age- and ethnicity-specific thyrotropin (TSH) reference limits decreases misclassification of patients with thyroid dysfunction. Developing such limits requires TSH measurements in different subpopulations. We determined, in the National Health and Nutrition Examination Survey III, the TSH median, 2.5th and 97.5th centiles as a function of age, and ...
